Main themes

This course provides an introduction to advanced methods of polymerisation. The course is made of projects. All topics are not necessarily covered each year. After recalling the basics of chain polymerization methods, the different current synthetic strategies will be studied (anionic, cationic, standard radical, controlled radical and coordinative polymerization methods). The scope and limitations of each method will be systematically discussed. Mechanistic and kinetic features will be then studied for each polymerization method. Special emphasis will be finally placed on the control of macromolecular architectures.

Aims

At the end of this learning unit, the student is able to :
1	The course aims at providing a deep knowledge of chain growth polymerisation methods. At the end of the course, the students will master the state-of-the-art in chain growth polymerisation methods, the links between controlled and living polymerisation methods and the molecular characteristics of the resulting chains (molar mass, chain dispersity, architecture), and the technological gridlocks facing chain growth polymerisation. Additionally, the students will be able to use the above-mentioned concepts in order to propose relevant synthetic methods for specific cases.   The contribution of this Teaching Unit to the development and command of the skills and learning outcomes of the programme(s) can be accessed at the end of this sheet, in the section entitled ¿Programmes/courses offering this Teaching Unit¿.

Teaching methods

Part A "Chain polymerization methods"
The chemistry part is based on a self-learning system. Scientific reviews, dealing with the main polymerization methods, will be provided and will be analyzed in small groups. Each student will work on three projects (polymerization methods). The self-learning will be conducted for two to three weeks during which the students and teachers will meet to discuss the reviews and prepare a presentation summarizing the reviews (see schedule). The students will then present orally their project before the whole class, followed by questions. This self-learning process will be evaluated by the teachers.
Part B "Physical chemistry of polymers in solution"
The physical chemistry part is made of six classes in flipped classroom format, in which the students resolve small problems and discuss concepts with the teacher, based on a prior reading of a section of the lecture notes and/or on watching podcasts. Before each class, the students have to answer a few questions on their preparative reading (quizzes); their answers are used by the teacher to identify misconceptions and tune the content of the classes.

Evaluation methods

Part A "Chain polymerization methods" (3 credits)
Part for the work performed during the year (continuous evaluation) and part for the written exam. The written exam consists of solving cases similar to those studied during the course.
Part B "Physical chemistry of polymers in solution" (2 credits)
Part of the points for the exam and part for the answers to the preparative quizzes. Before each class, the students are asked to answer a web-based quiz on the notes/videos they were asked to read/watch. This part is graded based on effort, not correctness of the answers. The exam may involve solving small problems similar to the ones solved in class, and may comprise more theoretical questions on some part of the course.

Other information

Written notes and reference books will be made available for the students. The course could be partly or totally delivered by an invited lecturer.

Online resources
